new and useful Improvements in Hand Broadcast-Seeders; and we do hereby declare that; the following is a full, clear, and exact de scription er the same, reference being bad to the annexed drawmgs, making a part of this specification, and to the letters and figures of; reference marked thereon.

The present invention has relation to certain new and useful improvements in. hand broadcast-seeders; and it consists in the details of construction, substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A repre sents the usual flexible grain-holder, which may be provided with means for suspending it from the operator, said flexible holder being connected to the hopper B, through which the grain is discharged. This chute or hopper B is connected to the upper side of a rectangular base, 0, having at its forward end a transverse opening, a, for the discharge of the seed onto the usual distributer-wheel, D, secured to the vertical drum b. The drum 1) is rigidly connected to a spindle, 0, having its bearings in the base 0 and the longitudinal brace E. The distributing-wheel is caused to revolve by means of the cord d,which is wound around the drum 1) and its ends or extremities fastened to the ends of a reciprocating rod, F, provided with coiled springs 0, one upon each end of the rod, to form. buffers when coming against the ends of the transverse bracket G. The upper end of the spindle 0 is provided with an eccentric,

the forward end of a feed-plate, H, by which means the feed-plate is given a lateral reciprocating motion as the wheel is revolved. This wheel D consists of a concave f, which works in a yoke,

wings k, as shown more clearly in Fig. 1. The feeding-plate H is cast or otherwise provided with a bar, Z, which extends back from the rear of the plate, and is pivoted at its extremity. to a lever, I. I is pivoted to the base 0, and its opposite or free end passes through a-guide and stop, m, which limits the movement of the lever. By moving back the lever the feeding-plate will also be carried back from under the opening h in the hopper, thus charge of the seed when the eration, a suitable spring, a, forcing the lever back to its normalposition when released by the operator.

In order. to limit the extent to which the feeding-"plate H is to be drawn back in controlling the discharge of the seed through the allowing the free dismachine is in op- .bottom, h, with radial arms i and separating- I One end of the-lever I opening a, agage-rod, J, is provided, against I I which strikes the stroke or backward throw of the lever Land the feeding plate' correspondingly, whichregw lates the opening in the hopper-f A curved guard, K, extends transversely under the base G in the rear of the distributingewheel 'D,wthe

lever I, thus limiting the ends projecting some distance beyond the sides of the base, which prevents the seed from being thrown to the rear of the machine.

The metal bracket G, ing for the reciprocating rod F, consists of a rectangular plate or bar having its ends turned up, with holes through which passes the rod. The advantages of this bracket are that it prewhich forms a bearvents all wear and tear on the wooden portion of the machine and confines all such wear and tear to the upwardly-bent ends of the bracket,

the ends of the spiral springs on the rods striking against them, and not against any other part of the machine.

rectly under the distributing-wheel D, gives the seed a chance of being distributed freely and not coming in contact with any obstacle, such as the cord of the rod. The seed as his the curved guard K, which is made very wide.

The drum b, being di- All the seed is freely scattered and distributed,

and none drops down by the operator.

the employment of the spring nthe front edge of the feeding-plate H is kept pressedtightly against a transverse flange, p, which efl'ectually 9s v distributed from the wheel D strikes against sides, against which prevents the escape of seed when the machine is not in operation, forming a tight joint between the two.

The feeding-plate H differs from others heretofore in use, in that it has a flanged rim, r, projecting upward and extending along the rear and right and left sides of the plate. This flanged rim is cast with the plate, and the advantages of such construction are that it effectually closes the discharge-opening in the hopper and prevents the seed from working out at the sides and rear of the plate, while the strip-0r flange in front of the opening prevents the seed from escaping at that point. The raised edges or flanged rim of the feedingplate is held against the under side of the base 0 by means of a transverse rod, L, removably connected to said base. The rod L, which I shall term a clamping-rod, may be held against the feeding-plate with any degree of tightness by setscrews s, which also removably secure the rod to the base 0.

In order to strengthen the point of connection between the plateH and arm Z, that part of the arm where it meets the plate is cast with a bifurcation, as shown at t, and the front of said plate is cast with a frame, M, terminating at its forward end in a yoke, 9, hereinbefore described. The plate H is formed at its front edge with the usual feed-distributing recesses,u. The outer or under side of the feeding-plate H is cast with bearing-ribs c at its the transverse clampingrod comes in contact, so as to prevent the surface of the plate coming in contact with the rod throughout its entire length, thereby decreasing the frictional surface between the rod and plate when the latter has imparted to it a lateral reciprocating nal motion by means of the lever.

The peculiar construction of the plate for.

motion and a longitudifeeding the seed to the wheel is considered important and essential in rendering it successful in its operation,and the adjustable and detachable clamping-rod serves most effectually to steady and guide the feeding-plate in its movement, as well as to keep the flanged rim upon the inner or upper side thereof snugly against the under surface of the base 0.

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a hand broadcast-seeder, a laterally reciprocating or vibratory feeding-plate, cast at its front or outer edge with a frame and yoke and having an upwardly projecting flanged rim extending along the rear and right and left sides, in combination with a suitable lever and gage-rod for operating the plate,and a clamping-rod extending across the plate upon the under side thereof, substantially as and for the purpose set forth.

2. In ahand broadcast-seeder, a suitable grain holder and hopper, a distributing-wheel, and means for operating it, and a transverse flange or strip secured to the under side of the base of the hopper in front of the discharge-opening, in combination with a feed-plate provided with a pivoted hand-leverand gage, said'plate having an upwardly-projecting flanged rim along the rear and sides,and bearing-ribs upon the outer or under side of the plate, and a clamping-rod for holding the same in position, substantially as and for the purpose specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
